MAX6363LUT23+T

Overview

The MAX6363LUT23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a reset threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device provides a 280 ms reset delay time and draws a typical operating supply current of 15 uA. It utilizes an SOT-23-6 package for surface-mount installation and supports a battery backup switch function. The output type is active low push-pull, and it lacks manual reset or watchdog timer capabilities.

Feature Summary

• Integrates a low-power microprocessor supervisor with a dedicated battery backup switch for seamless power source transitions.
• Provides precise voltage monitoring with a fixed 2.32 V threshold and 280 ms reset delay to ensure system stability.
• Features an active low push-pull output driver compatible with standard digital logic interfaces.

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup power switching
• Portable electronics needing low quiescent current supervision

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance documentation matches the specific batch. Check for obsolescence notices as the part may be subject to discontinuation. Ensure the SOT-23-6 package variant matches design requirements. Validate electrical parameters against the official datasheet before integration.

Selection Notes

Select this component when a fixed 2.32 V threshold is required for single-input voltage monitoring. Consider the 15 uA supply current for battery-sensitive designs. The absence of a watchdog timer and manual reset input limits flexibility compared to other series members. Verify that the active low push-pull output suits the target controller interface. Evaluate thermal performance within the specified -40 C to +85 C operating temperature range.

Part Context

This part belongs to the MAX6363L series of low-power MPU supervisors from Analog Devices/Maxim Integrated. It shares functional similarities with other variants like the MAX6363PUT23+T but differs in output configuration and threshold specifications. The series focuses on compact SOT-23 packaging for space-constrained applications. It serves as a dedicated power management IC for ensuring reliable system resets during voltage fluctuations.

FAQ

Does the MAX6363LUT23+T include a manual reset input?

No, the MAX6363LUT23+T does not feature a manual reset input; it relies solely on automatic voltage monitoring for reset generation.

What is the reset delay time for this supervisory circuit?

The reset delay time is 280 ms, providing a fixed timeout period after the voltage exceeds the threshold before asserting the reset signal.
